' cAP-mAKmG mAcHm To all whom it may concern: Be it .known that we, RUDOLPH H. BECK, a

citizen ofthe United States, and HENRY J.

. uid' from them.

It is further desired to so construct the machine'for accomplishing the above-noted object that it shall not only be substantial andnot likely to get out of order, but shall also be relatively simple as to the arrangement of its parts and eflicient in operation.

Another object of the invention is to provide a. novel device for cutting articles, such as paper caps for bottles,.from a sheet of paper or cardboard, which, after causing a die to sever and remove a cap or caps from such sheet, shall return said piece to the hole in the.

sheet from which itwas originally cut, and

by causing motion of said sheet thereby convey the piece or pieces to any desired point.

The invention also contemplates a novel device for punching or cutting a succession of pieces from a sheet of material 1n comblnation with means for automatically removing said pieces from the holes in the sheet from which-they have been cut. i

More particularly by our invention we propose to provide a machine for simultaneously cutting a number of paper caps for milk-bottles from a continuous sheet of cardboard and causing the sheet itself to act as the conveyer for removing the cut-out caps from the vicinity of thepunches, thereafter causing auto-' Qmatic mechanism to periodically displace the caps from the holes in said sheet. Our machine provides for caps so removed a conveyer which deposits them in a vessel containing liquified paraffin and employs adevice which,

after permitting each cap or series of caps cut by one operation of the machine to remain in the-liquid for a predetermined time,

delivers the capsto a pair of squeeze-rolls,

which remove the surplus liquid still adhering to them.

These objects We attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a sectional elevation showing the detail arrangement and construction of the parts comprising ourinivention. Fig. 2 is a plan view, partly in section, taken on the line 2 2, Fig. 1. Fig. 3 is a sectional elevation of our machine, taken on the line 3 3, Fig. 1, and

Fig. 6 is a plan View of a portion of our-machine, illustrating the means by' which a suecessive series of cutout caps are removed from the sheet of paper from which they have been cut and by which they have been conveyed from the punches; and Figs. 7 and 8 are sectional elevations illustrating in detail the construction and operation of a single one of the punches for cutting the caps from a sheet of cardboard. While we have'shown in the above drawings and shall. hereinafter describe our machine as applied to the manufacture of pasteboard caps, it will be understood that the device may be employed to cut out from a sheet of material any-desired form of piece, depending solely upon the punch and die used, and while we have employed parafiin for saturating our caps it will be understood that the device is applicable for coating or saturating pieces of any form or material with any desired liquid. 1

In the above drawings, 'A is a base=plate carried by a pair of standards or frames a and in turn carrying two other standards a at each side. These latter standards are provided with bearings f?! the main shaft a of the machine, upon whi ch is a fly-wheeler ahd fast and loose pulleys a and a Thereare also upon said shaft two eccentrics a and straps b, to which is connected 2. reciprocable head B,

. larged lower portions, so as to providea shoulder, as shown in Figs. 7 and 8, inengage'ment with the lower face of the casting and being held in their respective recesses by setscrews 0. Each punch is provided with a die or plate I), held in its face portion by means of a bolt 1), which plate is provided with type for printing upon thepieces cut out. Held in any desired manner to'the base-plate A and immediately under the punch-carrying head If is a plate (J, provided with a series of dies 0, which are retained in position by set-screwsc' and so placed as to coact with the punches b Immediately above said dies is a transverselyextending plate 0 serving as astripper for preventing the sheet of material operated upon from being lifted by the punches on their upward movement. There is extending into each of the dies 0 a plunger 0, supported in recesses of the head E, each of which is provided with a spring 0', whose pressure upon its plungers may be adjusted by a pair of nuts 0 screwed upon the threaded end of a bolt fastened to or forming part of the said plunger. The head E is carried upon a pair of arms a, each slidably mounted upon a vertically-placed bar F, whichhas at its lower end a threaded collar f, held in position by means of a set-screw f. A nut f 2 is placed between this collar f and the arm a", so that by revolution of this nut said arms, and with them the head E, together with the plungers' carried thereby, may be raised or lowered to any desired extent. There are in the arms (1* set-screws a by which said arms may be rigidly held, to the bar F after having been once adjusted.

Suitably carried by each of the standards (0' area pair of guides g and g, suitably'placed to secure wheels or. rollers g upon the shaft of an inking-roller Gr, so as to direct this latter into contact with the type carried by the various punches. Connected to said shaft g are a pair of arms 9, fastened to the ends of levers q upon a shaft g, journaled in the standard a. anism by which this shaft is oscillated to cause the roller Gr to .be moved. periodically under the punches, and this includes a gear a on the main shaft a meshing with a gear h on a shaft H, which shaft also carries a cam h in engagement with a roller k upon a slotted arm h. slot in said arm, which has adjustably connected to it ase'cond arm g fixed in turn to the shaft g By this means the revolution of the main shaft a causes the cam it to reciprocate the slotted arm h", and hence to escillate the shaft g as required.

Extending parallel to the face of the roller G are a'pair of rollers 11 and 71, having a res- In Fig. 5 is shown the mech-' The shaft H extends through the;

ervoir 5 from which they are supplied with ink. Pawl-and-ratchet mechanism l (shown in Fig. 5) is provided for the purpose of turning these rollers, and it will benoted that the connection between the arms [b and is so adjusted that on 'each stroke the roller G isguided into contact with the lower roller 11' by means of a small cam-surface '13, which is placed, as shown in Fig. 1, to engage the rollers g In order to feed card-board or other sheet materiallto the machine, we provide a pair of nip-rolls k andfk and periodically turn one of these by means of a ratchet-wheel I0 fas tened to a shaft of the roll 7x: and acted upon by a'pawl k carried on an arm $1 To the .end of the arm is connected a rod 7:, pinned to a crank in on a shaft K, operating in bearings in the lower standards or frames a, which shaft is continuously driven by means of a chain or belt is, extending between sprocketwheels upon said shaft K and upon the main driving-shaft a Upon the side of the punches and dies opposite to the nip-rolls and slightly below the level thereofis a conveyer belt or apron L, mounted upon a pair of rollers Z and l, which by reference toFig. 5 will be seen to be operated by a chain l engaging suitable sprocket- Wheels carried by said rollers and also a sprocket-wheel upon the shaft K, which is driven as above noted. Extending over the 'conveying-belt-L is a bar m, upon which are carried a series of fingers m, so placed that their ends are directly above and in the line of motion of the caps cut from the sheet of material operated on. part of a frame M, pivotally supported on a transversely-extending rod m it being noted that the side members of said frame extend to the rear of this rod and carry weights m by'which the bar m and its attached fingers are normally maintained in an elevated position. Pins m pass through the respective weights and are adjustably held in engagement with the edges of a container P by means of set-screws m thereby rendering possible the regulating of the position of the frame M. Said container is used to hold and keep melted a body of paralfin, as shown in Fig. 1, there being under it a perforated gaspipe 19 of the construction well known in the art, which is inclosed by the suitably-formed sides of the container.

Extending from the edge of the container Said bar 'mf formsl porting-frame 1",having standards '2", in which are. ournaled the shafts R and S. The

Said two chains are connected at intervals by crossbars 1 from which project a series of pins or lingers If, so placed that there are two of them to each of the; guideways formed by the bars and p of the screen 1). The shaft q -is driven by a chain 1 passing around suitable sprochot-wheels r audl', respectively, upon it and on the shaft it, while this latter shaft is driven by a chain'r', which engages sprocket-wheels r and A upon it and upon U the shaft Ii, respectively.

It will be seen that the container'P is car ried upon the arm or bracket-P, supported directly from one of the standards (1/ of the machine, and said bracket also carries a sup- I former of these shafts carries a hollow roll i 1 having a felt covering r and coacting with pa second hollow roll x, carried by the shaft S, which is also hollow. are provided with burner attachments, as shown in Fig. 2, whereby they may be supplied with gas from a pipe 91 and heated. From Fig. 5 it will be seen that the shaft S, and consequently the roll x, are positively driven by a gear a, meshing with a-second gear carried by the shaft R. A' relatively ""sinall roll 'iis placed to receive the paper caps 4o. i liver them to the squeezerolls' r' and a, there fbci'ng'a belt 1, (shown in Fig. 1,) actuated "from the shaft driven.

As soon as the sheet passes under the line of punches and dies-the actions illustrated in FigsIT and '8 take place- (a, the punches are forced through it and carry the pieces cut therefrom below the sur-- Bothof these shafts rolls, carrying with it all of the pieces that 'have been cut out.

After the punches have made a second stroke and again cleared the sheet the line of caps first formed is brought immediately under the line of lingers m, and

when the third stroke is made by the machine an arm 1:, carried by the reciprocating punchhcad B, is brought into engagement with the finger-carrying bar m, turning theframe M upon its pivot-shaft and forcing the fingers 111 against the pieces still carried by the sheet of material board. Such action forces said pieces out of the holes in the sheet and deposits them upon the conveying-apron L, from which they are delivered to their respective guideways in the screen p. The pins 11", carried by cross-bars q", will engage a set of caps and after moving them through the melted parafiin withinthe containei-Pwill push them upwardly along their guideways, seas to permit most of the surplus liquid .to drain from them and finally deliver them to the roll T. From here theyare passed through the sq ueezerolls 1- and s, which being heated quickly remove whatever surplus material still adheres to said caps and discharge them I into any desired receptacle or receptacles. The felt or other covering 1' upon the roll r is designed to absorb. the surplus liquid from the caps; but it isobvious that, if desired, other means may be provided for disposing of said liquid. After passing under the fingers m the sheet of material from which the pieces have been punched is guided over the machine by bars 1;, as indicated by the dotted lines in Fig. 1,

and disposed of in any desired manner.

By providing type in the punches and means for periodically inking the same we are enabled to simultaneously cut out and print each cap in the manner well-known to'the art, while by providing separate guideways for the caps delivered from each punch it is possible to produce and separately deliver caps each with different matter printed upon them.
